Ordered held without bail, Markoff is charged with murder, armed robbery, unlawful possession of a firearm, and kidnapping.

The charges, according to the Boston Police Department, are in connection with the April 14 murder of Julissa Brisman at the Copley Marriott Hotel in Boston and the April 10 kidnapping and robbery of another woman at the Westin Hotel, also in Boston.

In the Julissa Brisman murder case, in Boston, forensics technology”led to the recovery of an abundance of cellular, wireless and other electronic evidence,” Wark said.

He added that investigators from the Boston police homicide unit were able to link the IP address that was used to send an e-mail setting up the April 14 date with the murder victim to Markoff’s home address.

Brisman, according to information released by the Boston Police Department, was found at the Copley Marriott after having been shot three times in the abdomen at close range.

She also had been repeatedly struck in the head with a blunt object.

The woman had been advertising massage services on Craigslist.

The victim and assailant struggled in the doorway to a hotel room before Brisman was shot.

According to news reports, other hotel guests heard screams from Brisman’s room on the 20th floor of the hotel.

She was found lying in a pool of blood, riddled with bullet wounds — and a plastic restraint on one wrist. The massage table was reportedly set up in the room.
